Application filed January 25, 1909. Serial No. 474,141.

To all whom "it may concern:

Be it known that we, WILLIAM H. SPILL- MAN and ELMER M. BARNES, citizensof the United-States, residing at St. Joseph, county of Berrien, Stateof Michigan, have invented a certain new and useful Improvement inWagon-Poles, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this speciflcation.

This invention relates to wagon poles; it

= has for its object an improved wagon pole made from sheet metal, andarranged with adjustable connecting tongue hounds between itself and thehounds of the wagon.

In the drawing :Figure 1, is a plan view of the hounds end of the poleand the connection between the pole and the hounds. Fig. 2, is a crosssection of the pole. Fig. 3, is a perspective view of a portion of atonguehound. Fig. 1, is a side elevation of the end of the pole. Fig. 5,is a section, on an enlarged soale,'through the rear connection betweenthe hounds and the pole.

The pole proper is made from four pieces of heavy sheet metal stavemembers 1, 2, 3, and 4, each of which is formed to produce alongitudinal channel with a curved web uniting two flan es 1 and 1 2'The flanges 1 1 are radial to the cross section of the pole. A sidemember 2 of the pole is made in similar I shape, with a curved web andthe flanges 2 and 2'. Four of these channel members, larger at thehounds end of the pole, than at the front end of the ole, are joinedtogether, and bound together by hoops 5, 6, 7, 8, and 9. The two fronthoops 5 and 6 are united by a bar 10, from which projects the holdback11, made as a unitary casting, with the hoops 5 and 6, preferably madefrom malleable iron. At the rear end of the pole, the members are boundtogether by trunnion bearing hoops 8 and 9. The trunnions are perforatedand adjusting sleeve bolts 12 and 13 are inserted in the screw threadedopenings of the trunnions and in screw threaded sleeves 14 and 15 whichen age between the sleeve bolts and the hound members 17 and 18. Thehound members are channel members, with the Web 17 out suitably to allowthe channel member to bend at the angle 19, and the web part of themember in front of the out at the angle 19 is narrowed untilit vanishesat the extreme front end; the front end of the hound is inserted underhoop under which hoop the hound member has a slight play, to enable thehound member 17, as a whole, to be drawn closer to the body of the pole,or expanded farther away from the body of the pole by turning the sleevemembers 12 and 13, thus making the hound members adjustable in width, sothat they may engage between wa on-hound members 22 and 28, on wagons 0different make the adjustment need not be great, as the range ofvariation between the hounds of different wagons is not great, but issufficient to require that a pole which shall be commercially salablefor use with any one of many different makes, shall have someadjustability at this connec tion. Y

The pole, as a whole, is held to the hounds by bolts 24 and 25, whichpass through the hounds, through the tongue-hounds 17 and 18, throughsleeves 14 and 15, through'the trunnion ring 9, and through the sleevemembers 12 and 13. The connection by which bolt 25 en ages through thehoop 8 is precisely simi ar. At the angle 19, the side flanges of thebrace tongue-hound 17 overlap the flanges on the rear part of the hound,la ping by the flanges on the front part of t 1e member, and when thereis occasion to adjust the hound members, as above men tioned, the memberis bent at this part to make the necessary adjustment. As thisadjustment generally is made only on the first occasion of use, and notafterward, the bending is not frequently repeated.

The upper face of the hoop or ring 8 is flat surfaced to form a bearing8 for the doubletree, and a hammer guard'26 pivoted to the rear hoop 9,and provided with a hole 27 to register with the hole 28, is arranged toengage over the doubletree.

What we claim is 1. The combination of a wagon pole composed of aplurality of flanged stave members abutting'laterally one againstanother, encircling bands holding the same in assembled relation, houndmembers engaging with their forward ends between one of said bands andthe pole, and adjustable means for holding the pole and the houndmembers in desired relation to one another, substantially as described.

2. In combination, a wagon pole, comprising a plurality of correlatedstave members, each having flanged edge portions adapted to be broughtinto contact with the of the pole may be regulated, substantially ascorresponding parts of adjacent members, described.
